San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.
San Diego Rat Control Tip of The Week
Non-lethal Ways To Get Rid Of Rats
If you are the type that considers rats as small cute-looking creatures, you might feel bad for wanting to kill them because they are causing a nuisance in your home. The fact is, your feelings do count. But at the same time, you can't afford to continue watching as these little creatures destroy your home and put your life at the risk of contracting diseases.
We understand how you feel, which is why we will be sharing non-lethal ways to get rid of the rats in your home. With this, you will be able to get rid of the rats without actually killing them.
1. Get A Cat
Cats and rats are natural enemies. If you have a cat in your home, rats will try as much as possible to do all they can to avoid your home. The sound and smell of the cat alone will trigger the sense of the rats and will make them stay as far away as they can. With this method, you will be able to get rid of the rats in your home without even having direct contact with them.
2. Trap And Release
This is another way to get rid of the rats in your home, the only issue with the use of this method is that cannot be used in a home where there are many rats. This is mainly because rats are smart and will end up figuring out that it's a trap after they see it capture one or two other rats. To trap and release a rat, all you need is a live trap and bait.
Also, you need to understand the fact that when you capture a rat and release it into another environment, its chances of survival are very slim.
3. Use Natural Rat Repellent
Just like other animals, rats are sensitive to some smells and they will do all they can to stay away from those areas. You can take advantage of this as well and use it to get rid of the rats in your home. A mixture of cayenne pepper and peppermint will help you get this done.
